A disconnect mechanism (10) for a secondary driveline (12) and method of assembly can be used in an all-wheel drive (AWD) vehicle having a rear driveline module (RDM) (20) for changing drive modes between a two-wheel drive mode and an AWD mode. The disconnect mechanism (10) can include a hydraulically actuated coupling clutch (34) connected to a power take-off unit (PTU) for transferring rotary power from the PTU (36) to the RDM (20) during the AWD mode, a hydraulically actuated first and second rear clutch (30, 32) for rotationally connecting and disconnecting corresponding first and second rear axles (14a, 14b) drivingly coupled to rear wheels (16a, 16b) during the AWD mode and two-wheel drive mode, respectively, and a hydraulic actuating assembly (40) including a source of pressurized fluid (44) for actuating the coupling clutch (34), the first rear clutch (30), and the second rear clutch (32), and for synchronizing any speed differential therebetween.
